The present application relates generally to digital video recording ofvideo programming or broadcasts. More particularly, example embodimentsare directed to a system and method to account for scheduling changes inprogramming with an update of a digital video recorder (DVR) recordingschedule.

BACKGROUND

Recent developments in digital technology have spurred the developmentand deployment of digital video broadcasting services. The digital videobroadcasting services not only broadcast high quality video programming,including high-definition (HD) programs, but also provide the ability tobroadcast data including electronic program guide (EPG) data. Digitalbroadcast programs are typically provided by satellite broadcasters,terrestrial broadcasters and cable broadcasters. More recently, digitalbroadcast programs have also been deployed via the Internet Protocol(IP) by major telecommunication provides.

Video broadcasters have traditionally distributed video broadcasts toviewers using a variety of broadcasting standards, including the analogNational Television Standard Committee (NTSC) standard. More recently,with the constant expansion of the number of video broadcast channels,HD video broadcasts and provision of data (including EPG data), all ofwhich have placed a premium on bandwidth for transmission, thedistribution of video broadcasts has been achieved via digitalstandards, including the Advanced Technical Systems Committee (ATSC)standard. Other digital standards which have been used include theMoving Picture Experts Group H.262 (MPEG-2) standard, the H.264 (MPEG-4)standard and the Digital Video Broadcasting (DVB) standard. While theforegoing standards provide for in-band transmission of EPG data withthe transmission of the video programming, typically EPG data has beenprovided out-of-band from the video programming by third-partyaggregators of programming schedules, such as Tribune TV and Gemstar.

Digital video broadcasts are transmitted or distributed from theaforementioned video broadcasters to an end user's digital set top box(STB) which decodes the digital video signal for display on a videodisplay device (e.g., television). The digital video signal may bereceived by the STB via a satellite dish, a coaxial cable, a telephoneline (including digital subscriber line (DSL)), Ethernet, and the like.As described above, the EPG data may transmitted in-band with orout-of-band from the digital video signal being transmitted. Typically,satellite broadcasters and cable broadcasters have allocated respectivecarrier frequencies for receiving events or requests from the STB(including requests for EPG data) at two-way digital head ends andtransmitting non-video related data (including EPG data) to the STB. Asdescribed hereinabove, such EPG data is typically obtained from thethird-party aggregators of programming schedules.

Recent advancements in digital video recording technology in set topboxes have further incorporated digital video recorder (DVR)functionality into the STB for recording digital video broadcasts to adigital storage medium (e.g., hard-drive, optical storage, and the like)and playing back the recorded digital video broadcasts to the videodisplay device. Further advancements in video recording technology haveyielded the virtual DVR, where video head ends provide digital videorecording functionality to the STB. The DVR functionality operates usingthe EPG data for scheduling the recording of particular videobroadcasts.

FIG. 1 is an example high-level block diagram of a video broadcastingsystem 100 that accounts for scheduling changes in programming withscheduling updates of a digital video recorder (DVR) 150 recordingschedule 154. The video broadcasting system 100 includes an electronicprogram guide (EPG) aggregator 105, at least one broadcast network 102,a super video head end (SHVE) 108, a video head end (VHE) 128, a set topbox (STB)/digital video recorder (DVR) 150 and multiple video sources122-16 and 144-148. The SVHE 108 is interconnected to a video head end(VHE) 128. The VHE 128 is in turn interconnected to an end user's settop box (STB)/digital video recorder (DVR) 150. It is noted that forclarity and simplicity of the depiction one SHVE 108, one VHE 128 andone STB/DVR 150 are described. However, the broadcasting system 100 mayinclude multiple SVHEs 108; each SVHE 108 may be interconnected tomultiple VHEs 128; and each VHE 128 may be interconnected to multipleSTB/DVR units 150. The interconnection between the SVHE 108 and the VHE128 may be accomplished via a long haul transport network (e.g., gigabitEthernet network, Asynchronous Transfer Mode (ATM) network, frame relaynetwork) and the like. The interconnection between the VHE 128 and theSTB/DVR 150 may be accomplished via a fiber to the home (FTTH), fiber tothe node (FTTN), telephone (including digital subscriber line (DSL)),coaxial cable, hybrid fiber/coaxial, and combinations thereof. Alternateconnections may also be employed to interconnect the SVHE 108 to the VHE128 and the VHE 128 to the STB/DVR 150.

Now with particular reference to the SHVE 108 of FIG. 1, the SVHE 108includes a video reception module 120 that receives video programming ofvideo broadcasts from multiple video sources, including off-air antenna122, satellite receiver 124, as well as any other video sources 126,which may include fiber feed sources, video servers and tape machines,which serve video programming. The video programming received by thevideo reception module 120 may be in a variety of formats, includingNTSC, ATSC, MPEG-2, MPEG-4, DVB, Windows Media, baseband digital, andother available formats. The SVHE 108 further includes a videodistribution module 118 that cooperates with the video reception module120 to distribute the video programming received by the video receptionmodule 120 to a video broadcast/switch module 140 of a video head end(VHE) 128 (described in further detail herein below). More specifically,the video reception module 120 may decode (via video decoders) the videoprogramming received in the aforementioned different formats into astandardized format. In turn, the video distribution module 118 mayfurther encode (via video encoder) the video programming provided in thestandardized format by the video reception module 120 into a digitalformat for ultimate distribution to the STB 150 (e.g., MPEG-2, MPEG-4and the like). The video distribution module 118 may further multiplex(e.g., via statistical multiplexing) video broadcasts of multipledigital video broadcast channels over one carrier frequency allocation(e.g., 6 MHz or 8 MHz), which is a typical carrier frequency allocationthat may be used for one analog channel.

Further with reference to FIG. 1, the SVHE 108 also includes anelectronic program guide (EPG) reception/extraction module 116, whichmay receive EPG data from and EPG aggregator 105 and may further extractEPG data from video sources 122-126. More specifically, the EPGreception/extraction module 116 may receive out-of-band EPG data fromthe EPG aggregator 105, which aggregates and maintains EPG data frommultiple broadcast networks (e.g., broadcast network 102). The EPG dataidentifies video broadcasts in accordance with the ATSC standard A/65(commonly referred to an event information table (EIT)), designatingtheir respective time slots and broadcast channels (e.g., carrierfrequencies coupled with transport stream identifier (TSID)). The EPGreception/extraction module 116 may further extract in-band EPG datafrom the video programming decoded by the video reception module 120,which is received from the respective video sources 122, 124 and 126.The video sources 122-26 may or may not provide in-band EPG data. Uponreceipt or extraction of EPG data, the EPG reception/extraction module116 may periodically (e.g., every day) update a main EPG database 112with the received/extracted EPG data for a predetermined time period(e.g., a two week period). The periodic update of the main EPG database112 may be on a scheduled basis (e.g., nightly) or may be on a real-timebasis. Upon the periodic update, the EPG reception/extraction module 116notifies the EPG distribution module 114 that a periodic update had beenperformed. Upon notification, the EPG distribution module 114distributes the EPG data in the main EPG database 112 to the VHE 128 aswill be described in greater detail below.

Still further with reference to FIG. 1, the at least one broadcastnetwork 102 is interconnected over a communication network 106 to theupdate web service 110 of the SVHE 108 and is enabled to provideout-of-band scheduling updates to the SVHE 108 for digital videoprogramming received via video sources 122-126. The communicationnetwork 106 may be any conventional network, including the Internet,Wide Area Network (WAN), Metropolitan Area Network (MAN), Campus AreaNetwork (CAN), wireless, satellite, as well as a variety of differentcombinations thereof. The communication over the communication network106 between the schedule update module 104 of the broadcast network 102and the update web service 110 of the SVHE 108 may be accomplished via avariety of different protocols, including transfer controlprotocol/Internet protocol (TCP/IP), hyper text transfer protocol(HTTP), extensible markup language (XML), as well as other well knownprotocols and communication methods.

Yet further with reference to FIG. 1, the web service 110 of SVHE 108may receive via the communication network 106 out-of-band schedulingupdates from a schedule update module 104 of the at least one broadcastnetwork 102. The at least one broadcast network 102 may include theAmerican Broadcasting Channel (ABC), National Broadcasting Channel(NBC), Central Broadcasting Station (CBS), Entertainment and SportsProgramming Network (ESPN), and the like. The communication between theschedule update module 104 of the at least one broadcast network 102 andthe update web service 110 of the SVHE 108 may be a framework thatsupports automated scheduling updates. The update web service mayfurther provide a secure framework, in which the update web service 110authenticates the at least one broadcast network 102 before authorizingtransmission of scheduling updates. It should be noted that the updateweb service 110 is not a primary means of receiving EPG data, rather itis used to convey last minute scheduling changes to mitigate any delayin receiving such data given the periodic nature of the updates from theEPG aggregator 105 or video sources 122-126. Each of the at least onebroadcast network 102 may occasionally update via its schedule updatemodule 104 the scheduling of certain video broadcasts. Morespecifically, the scheduling updates may be employed when regularlyscheduled video broadcasts are pre-empted by other video broadcasts(e.g., State of the Union Address, emergency broadcast and the like) ora time slot of a regularly scheduled video broadcast is changed toanother scheduled time slot. The scheduling updates may also be employedwhen a start time or a stop time of a regularly scheduled videobroadcast is changed. This may occur when a regularly scheduled videobroadcast is extended (e.g., sports event that lasts longer that thetime allotted), causing its stop time to be extended. It is to be notedthat the extension of one regularly scheduled video broadcast maynecessarily impact one or more of the start time and the stop time of alater regularly scheduled video broadcast.

Still further with reference to FIG. 1, when a broadcast network 102updates a regularly scheduled video program, the scheduling update istransmitted from the schedule update module 104 of the broadcast network102 via the communication network 106 to the update web service 110. Theupdate web service 110 receives the scheduling update and updates theEPG data in the main EPG database 112 with the scheduling update. Theupdate web service 110 further notifies the EPG distribution module 114of the scheduling update. At a predetermined time, the EPG distributionmodule 114 reads the main EPG database to obtain scheduling updates anddistributes the scheduling updates to the EPG update module 130 of theVHE 128. The predetermined time may be a preset time interval (e.g.,every minute) or may be determined based on the number of schedulingupdates (e.g., every update), or any other variation or setting. Morespecifically, the EPG distribution module 114 of the SVHE 108 maycommunicate with the EPG update module 130 of the VHE 128 atpredetermined times in two distinct modes: transmitting a bulk updateincluding an entire EPG (multiple video broadcasts) from the main EPGdatabase 112 for a certain date/time duration, or transmittingtransactional scheduling updates for specific video broadcasts.

Now with particular reference to the VHE 108, the VHE 108 includes avideo reception module 142 that receives local video programming orbroadcasts from multiple video sources, including off-air antenna 144,satellite receiver 146 and other video sources 148. The local videoprogramming received by the video reception module 142 may be in avariety of formats, including NTSC, ATSC, MPEG-2, MPEG-4, DVB, WindowsMedia, baseband digital, and other available formats. The other videosources 148 may include fiber feed sources, video servers and tapemachines, which serve video programming. In addition, the other videosources 148 may also include video programming received via telecomtransport networks directly from a broadcaster in any of the foregoingformats. The VHE 128 further includes a video distribution module 138that cooperates with the video reception module 142 to distribute thelocal video programming received by the video reception module 142 to anend-user's STB/DVRs 150. Similarly to the video reception module 120 ofthe SVHE 108, the video reception module 142 of the VHE 128 may decode(via video decoders) the local video programming received in theaforementioned different formats into a standardized format. In turn,the video distribution module 138 may further encode (via video encoder)the video programming provided in the standardized format by the videoreception module 142 into a digital format for ultimate distribution tothe STB/DVR 150 (e.g., MPEG-2, MPEG-4 and the like). The videodistribution module 138 may further multiplex (e.g., via statisticalmultiplexing) video broadcasts of multiple digital video broadcastchannels over one carrier frequency allocation (e.g., 6 MHz or 8 MHz).Furthermore, the video programming from the video distribution module118 of the SVHE 108 and the local video programming from the videodistribution module 138 of the VHE 128 are distributed to the videobroadcast/switch module 140, which broadcasts or switches channels ofthe video programming from the SVHE 108 and the VHE 128 to a videoreceiver module 160 of the end-user's STB/DVR 150 (described hereinafterin greater detail).

Further with reference to the VHE 128 of FIG. 1, the VHE 128 includes anEPG update module 130 that receives both periodic updates and schedulingupdates from the EPG distribution module 114 of the SVHE 108. Uponreceipt of an update (e.g., periodic or scheduling), the EPG updatemodule 130 updates the local EPG database 132 and notifies theEPG/schedule process module 134. Upon notification, EPG schedule processmodule 134 may distribute the update (e.g., periodic or scheduling) toan update module 156 of an end user's STB/DVR 150 automatically.Alternatively, the EPG schedule process module 134 may distribute onlythe periodic updates automatically and may await a request to distributea scheduling update to the update module 156 of the STB/DVR 150.Typically, the periodic or scheduling updates may be distributed atpredetermined time or times (e.g., such as early morning), or when theupdate is requested by the STB/DVR 150.

Still further with reference to the VHE 128, the VHE 128 also includesan electronic program guide (EPG) extraction module 136, which extractsEPG data from the local video programming received by the videoreception module 142 from the respective video sources 144, 146 and 148based on a change notification signal in the video programming. It isnoted the bulk of the EPG data is received via the EPG update module 130from the EPG distribution module 114 and inserted into the local EPGdatabase 132, as the updates (e.g., periodic or scheduling) are receivedby the VHE 128. The EPG data extracted from the local video programmingidentifies video broadcasts for a predetermined period of time (e.g.,typically two weeks to one month), their respective time slots, channeldesignations program descriptions and other video program relatedinformation. The EPG extraction module 136, upon receipt of the changenotification signal, periodically updates the local EPG database 132with the extracted EPG data. Upon the periodic update, the EPGextraction module notifies the EPG distribution module 134 that aperiodic update had been performed. Upon notification, the EPGdistribution module 114 distributes the periodic update to the STB/DVR150. Such distribution may be initiated by the VHE 128 at midnight, atwhich point an extra day of programming two weeks out is added to theEPG data, or initiated by the STB/DVR 150 when a user navigates to adate/time that is not locally stored in the EPG 152 of the STB/DVR 150,thus requiring a download of EPG data for required time).

Now with particular reference to the STB/DVR 150, the STB/DVR 150includes a video receiver module 160, a tuning module 162 and a displaymodule 164. The video receiver module 160 receives video programmingfrom the video broadcast/switch module 140 of the VHE 128. Upon channelselection by a user via a remote control 166, the tuning module 162 mayselect a particular channel from the video programming received by thevideo receiver 160 (if multiple channels including the channel selectedare being received) for display by the display module 164 on the displaydevice 168. Alternatively, upon channel selection by the user via theremote control 166, the tuning module 162 may request the video receiver160 to request the video broadcast/switch module 140 to switch the videoprogramming to the requested channel (if a non-requested channel isbeing received) for display by the display module 164 on the displaydevice 168.

Still further, the STB/DVR 150 further includes an en electronic programguide 152, a recording schedule 154 and an update module 156. The updatemodule 156 may glean from in-band EPG data associated with videoprogramming being received at STB/DVR 150 via video receiver module 160whether there is a scheduling update, and if so, may further update theEPG 152 and recording schedule 154 in accordance with the update. Theupdate module may further receive periodic or scheduling updates fromthe VHE 128. Upon receipt of a periodic update or a scheduling update,the update module 156 updates the EPG 152 and recording schedule 154 inaccordance with the update. For both of the above scenarios, the updatemodule 156 may or may not update the EPG 152 based on particularrequirements. For a periodic update (e.g., every day), the update module156 overwrites the EPG 152 with the periodic update and updates entriesin the recording schedule 154 with those included in the periodicupdate. For a scheduling update, the update module 156 updates entriesin the EPG 152 and recording schedule 154 that correspond to thescheduling update. As mentioned hereinabove, a particular videobroadcast may be pre-empted or its start time and/or stop time changed,etcetera. Upon pre-emption of a video broadcast, the video broadcast'scorresponding entries in the EPG 152 and recording schedule 154 may beupdated via a scheduling update. In the EPG 152, the description for theentry may be updated to reflect that the regularly scheduled videobroadcast has been pre-empted. In the recording schedule 154, thedescription for the entry may be updated to reflect that the regularlyscheduled video broadcast has been pre-empted and the start time and thestop time may be reset to “null” values (or recording schedule for thatvideo program may otherwise be disabled). Upon the change of the starttime and/or stop time of a video broadcast, the video broadcast'scorresponding time entries in the EPG 152 and recording schedule 154 areupdated to reflect the change of time.

Further with reference to FIG. 1, the STB/DVR 150 also includes a videorecording module 158 that may record a scheduled video broadcast andplay the recorded video broadcast via the display module 164 on thedisplay device 168. The video recording module 158 may poll therecording schedule 154 at predetermined time intervals or via othermechanisms may query the recording schedule 154 to determine whetherthere is a scheduled recording. Alternatively, notifications to thevideo recording module 158 to start and/or stop recording may betransmitted via system interrupts on the basis of the recording schedule154. In an embodiment in which scheduling changes are automaticallydistributed from the EPG/schedule process module 134 of the VHE 128 tothe update module 156, and upon a determination that there is ascheduled recording, the video recording module 158 may start recordingat the start time for the particular video broadcast to be recorded andmay stop recording at the stop time. It is noted that if the start timeand the stop time are “null” values (or if the video program isotherwise disabled for recording), indicates to the video recordingmodule 158 that no recording is to occur.

Still further with reference to FIG. 1, in another embodiment in whichscheduling changes are not automatically distributed from theEPG/schedule process module 134 of the VHE 128 to the update module 156(or not done so in a timely manner to impact a pending video recording),the video recording module 158 may request the update module 156 toobtain one or more scheduling updates for each scheduled recording. Morespecifically, the first one or more requests may be made atpredetermined times before the start time of the scheduled recording(e.g., two hours and/or two minutes before the start time of thescheduled recording) in the event that the scheduled video broadcast maybe broadcast earlier than the scheduled start time orpre-empted/rescheduled, respectively. For each of the first one or morerequests, the update module 156 may transmit a scheduling update requestfor the scheduled broadcast to the EPG/schedule process module 134,which in turn may query or interrogate the local EPG database 132 todetermine whether the start and/or stop times for the requested videobroadcast have changed, and may further return a result to the updatemodule 156. The result may be a scheduling update that includes a flag,which designates whether the start/stop times for a video broadcast areupdated, and additional data that may denote the video broadcast name,start time and stop time. A flag that is set to off (e.g., zero) mayrepresent to the update module 156 of the STB/DVR 150 that there hasbeen no scheduling update for the video broadcast. Alternatively, a flagthat is set to on (e.g., one) may represent to the update module 156 ofthe STB/DVR 150 that there has been a scheduling update for the videobroadcast. Upon receipt of a result with no scheduling update, theupdate module 156 may notify the video recording module 158 that noscheduling update is available, in which case the video recording module158 may record the scheduled video broadcast as indicated in therecording schedule 154. Upon receipt of a scheduling update, the updatemodule 156 may update the respective entries in the EPG 152 and in therecording schedule 154 in accordance with the scheduling update and maynotify the video recording module 158 that a scheduling update hasoccurred. Upon notification of a scheduling update, the video recordingmodule 158 polls the recording schedule 154 to determine whether thevideo broadcast for which scheduling was updated is to start at a starttime that is different than the regularly scheduled start time. If so,the video recording module may start recording the updated scheduledvideo broadcast at the start time indicated (as updated).

Additionally with reference to FIG. 1, once the video recording module158 has started recording a video broadcast at the indicated start time,the video recording module 158 may make a second request to the updatemodule 156 at a predetermined time before the stop time of the scheduledrecording (e.g., two minutes before the stop time of the scheduledrecording) in the event that the scheduled video broadcast may have beenextended. The update module 156 may transmit a scheduling update requestfor the scheduled broadcast to the EPG/schedule process module 134,which in turn queries the local EPG database 132 for the scheduledbroadcast and returns a result to the update module 156. The result maylikewise be a scheduling update, which will similarly include a flagindicating whether the stop time has changed for the scheduledbroadcast, and if so, will include an updated stop time. Upon receipt ofa result with no scheduling update, the update module 156 may notify thevideo recording module 158 that no scheduling update is available, inwhich case the video recording module 158 may record the scheduled videobroadcast as indicated in the recording schedule 154 (e.g., stoppingrecording at an indicated scheduled stop time). Upon receipt of thescheduling update, the update module 156 may update the respectiveentries in the EPG 152 and/or in the recording schedule 154 inaccordance with the scheduling update and may notify the video recordingmodule 158 that a scheduling update has occurred. Upon notification, thevideo recording module 158 polls the recording schedule 154 to determinewhether the video broadcast which is being recorded and for whichscheduling was updated is to stop at a later stop time. If so, the videorecording module may stop recording the updated scheduled videobroadcast at the stop time indicated (e.g., stopping recording at alater stop time).

As aresult, the video recording module 158 may continue to record thescheduled video broadcast 312 as updated by the scheduling update (e.g.,from 1:00 PM to 5:00 PM).

FIG. 5 is a flowchart that illustrates an example method 500 for theSVHE 108 to obtain and distribute schedule updates to the VHE 128 inaccordance with FIG. 1. The method begins at operation 502 in which theSVHE 108 receives an out-of-band electronic program guide (EPG) data forplural video broadcasts from an EPG aggregator 105. More specifically,the EPG reception/extraction module 116 receives the EPG data andupdates the main EPG database 112 with the EPG data. At operation 504,the SVHE 108 via the EPG reception/extraction module 116 extractsin-band EPG, which may include at least one schedule update, for one ormore video broadcasts, from the at least one video source 122-126. Atoperation 506, the SVHE 108 may receive one or more schedule updates foreach of one or more video broadcasts from at least one broadcast network102. More specifically, the SVHE 108 may receive the schedule updatesvia update service 110 from schedule update module 104 of the broadcastnetwork 104 using communication network 106. At operation 508, the EPGdata in the main EPG database 112 is updated with a corresponding entryin the extracted EPG and with schedule updates received from the atleast one broadcast network 102. More specifically, the main EPGdatabase 112 may be updated by the EPG reception/extraction module 116and the update web service 110. Lastly, at operation 508, the updatedschedules of video broadcasts in the EPG database 112 are distributed tothe VHE 128 at a predetermined a time via the EPG distribution module114.

FIG. 6 is a flowchart that illustrates an example method 600 for the VHE128 to receive and distribute schedule updates to the STB/DVR 150 inaccordance with FIG. 1. More specifically, the method 600 begins atoperation 602 in which the VHE 128 receives one or more schedule updatesfor one or more video broadcasts from the SVHE 108 via the EPG updatemodule 130. The schedule updates are used to update schedules ofcorresponding video broadcasts in the local EPG database 132. Atoperation 604, the VHE 108 via EPG extraction module 136 extractsin-band EPG, which may include at least one schedule update, for one ormore video broadcasts, from at least one video source 144-148. Atoperation 606, the schedules of the one or more video broadcasts areupdated in the local EPG database 132 with the received and extractedschedule updates via respective modules 130 and 136. At operation 608,it is determined whether a periodic update is to be performed at apredetermined time. If a periodic update is to be performed, the method600 continues at operation 622 in which the EPG/schedule process module134 distributes all available schedule updates for video broadcasts inthe local EPG database 132 to the STB/DVR 150. If however there noperiodic update to be performed, the method 600 continues at operation610 in which the VHE 128 via the EPG/schedule process module 134receives a schedule update request for a video broadcast from a STB/DVR150. At operation 612, the EPG/schedule process module 134 queries orinterrogates the local EPG database 132 as to whether a video broadcasthas an updated schedule. If at operation 614 it is determined that thevideo broadcast does not have an updated schedule the method continuesat operation 620 in which a null result for the schedule of requestedvideo broadcast is transmitted to the STB/DVR 150. Alternatively, if atoperation 614 the video broadcast has an updated schedule, the method600 continues at operation 616 in which the EPG/schedule process module134 retrieves the updated schedule for the video broadcast from thelocal EPG data base 132 and at operation 618 transmits the retrievedupdated schedule to the STB/DVR 150.

FIG. 7 is a flowchart that illustrates an example method 700 for theSTB/DVR 150 to begin recording of a video broadcast based on a scheduleupdate in accordance with FIG. 1. The method 700 begins at operation 702in which the update module 156 may glean from EPG data received atSTB/DVR 150 via video receiver module 160 whether there is a scheduleupdate a predetermined time before a start time of a video broadcast tobe recorded by the video recording module 158. The gleaning for theschedule update may be based upon a request for an updated schedule bythe video recording module 158 of the STB/DVR 158 in accordance withFIG. 1. At operation 704, it is determined whether an updated schedulefor the video broadcast was gleaned from the EPG data received at theSTB/DVR 150. If no updated schedule were gleaned, the method 700continues at operation 706 in which the STB/DVR 150 via update module158 may request a schedule update from the VHE 128 a predetermined timebefore a start time of the video broadcast to be recorded. At operation708, the update module 156 of the STB/DVR 150 receives a schedule resultfrom EPG/schedule process module 134 of the VHE 128. At operation 710 itis determined whether the schedule result includes an updated schedule(e.g., start time and/and end time) for the video broadcast to berecorded. If there is no updated schedule, the method 700 continues atoperation 718 in which the video recording module 158 of the STB/DVR 150begins recording the video broadcast in accordance with the recordingschedule 154 (e.g., start time) for the video broadcast. If however itis determined at operation 712 that there is an updated schedule for thevideo broadcast, the method 700 continues at operation 714 in which theupdated module 156 of the STB/DVR updates the recording schedule 154 forthe video broadcast. At operation 716, the video recording module 158 ofthe STB/DVR 150 begins recording the video broadcast in accordance withthe updated recording schedule 154 (e.g., start time) for the videobroadcast.

FIG. 8 is a flowchart that illustrates an example method 800 for theSTB/DVR 150 to stop recording of a video broadcast based on a scheduleupdate in accordance with FIG. 1. The method 800 begins at operation 702in which the update module 156 may glean from EPG data received atSTB/DVR 150 via video receiver module 160 whether there is a scheduleupdate a predetermined time before an end time of a video broadcastbeing recorded being recorded by the video recording module 158. Thegleaning for the schedule update may be based upon a request for anupdated schedule by the video recording module 158 of the STB/DVR 158 inaccordance with FIG. 1. At operation 804, it is determined whether anupdated schedule for the video broadcast was gleaned from the EPG datareceived at the STB/DVR 150. If no updated schedule were gleaned, themethod 800 continues at operation 806 in which the STB/DVR 150 viaupdate module 158 may request a schedule update from the VHE 128 apredetermined time before an end time of the video broadcast beingrecorded by the video recording module 158. At operation 808, the updatemodule 156 of the STB/DVR 150 receives a schedule result fromEPG/schedule process module 134 of the VHE 128. At operation 810 it isdetermined whether the schedule result includes an updated schedule(e.g., end time) for the video broadcast being recorded. If there is noupdated schedule, the method 800 continues at operation 818 in which thevideo recording module 158 of the STB/DVR 150 end recording the videobroadcast in accordance with the recording schedule 154 (e.g., end time)for the video broadcast. If however it is determined at operation 812that there is an updated schedule for the video broadcast (e.g., endtime), the method 800 continues at operation 814 in which the updatedmodule 156 of the STB/DVR updates the recording schedule 154 for thevideo broadcast. At operation 816, the video recording module 158 of theSTB/DVR 150 terminates recording the video broadcast in accordance withthe updated recording schedule 154 (e.g., end time) for the videobroadcast.

FIG. 9 is an example high-level block diagram of a video broadcastingsystem 900 that accounts for scheduling changes in programming withscheduling updates of a remote digital video recorder (DVR) service 170recording schedule 174. Video broadcasting system 900 of FIG. 9 issimilar to video broadcasting system 100 of FIG. 1, except that videorecording and scheduling updates are performed at the video head end128. More specifically, the VHE 128 includes a remote DVR service 170.The remote DVR service 170 includes a video recording module 172, arecording schedule 174 and an update module 176. The video recordingmodule 172 may record a scheduled video broadcast and may transmit uponrequest the recorded video broadcast to the STB/DVR 150 for display onits display device 168. The video recording module 172 may poll therecording schedule 174 at predetermined time intervals or via othermechanisms may query the recording schedule 174 to determine whetherthere is a scheduled recording to record. Alternatively, notificationsto the video recording module 172 to start and/or stop recording may betransmitted via system interrupts on the basis of the recording schedule174. The update module 176 may glean from in-band EPG data associatedwith video programming being distributed by video broadcast/switchmodule 140 whether there is a scheduling update, and if so, may furtherupdate the recording schedule 174 in accordance with the update. Theupdate module 176 may further receive periodic or scheduling updatesfrom EPG/schedule process module 134, which obtains the updates from thelocal EPG database 132 based on notification from EPG update module 130.It is noted that the EPG/schedule process module 134 continues totransmit the periodic or scheduling updates to the STB/DVR 150. Uponreceipt of a periodic update or a scheduling update, the update module176 updates recording schedule 174 in accordance with the update. For aperiodic update (e.g., every day), the update module 176 updates entriesin the recording schedule 174 with those included in the periodicupdate. For a scheduling update, the update module 176 updates entriesin recording schedule 174 that correspond to the scheduling update.

Further with reference to FIG. 9, the STD/DVR 150 of FIG. 9 is similarto the STB/DVR 150 of FIG. 1, except that the video recording andscheduling updates are performed at the video head end 128. Morespecifically, as noted above, the EPG/schedule process module 134 of VHE128 continues to transmit the periodic or scheduling updates to theSTB/DVR 150. The update module 178 receives these scheduling updates andupdates its EPG 152 with the updates. The scheduling/playback module 180displays the EPG 152 via the display module 164 on the display device168 to a user and enables the user to select a particular videobroadcast for recording or deselect a scheduled recording. Theselection/deselection of the particular video broadcast is transmittedby the scheduling/payback module 180 to the update module 178, which inturn transmits the selection/deselection to the EPG/schedule processmodule 134 of the VHE 128. Upon receipt of the selection/deselection,the EPG/schedule process module 134 notifies the update module 176 ofthe remote DVR service 170, which updates the recording schedule 174 inaccordance with the selection/deselection.

Still further with reference to FIG. 9, the scheduling/playback module180 also enables the user to play a recorded video broadcast. Morespecifically, the scheduling/playback module 180 enables the user toselect a recorded video broadcast for display using an appropriatedisplay via the display module 164 and display device 168. Thus, uponselection of the recorded video broadcast, the scheduling/playbackmodule 180 may use the tuning module 162 to tune to a channel forplaying the recorded video broadcast. The tuning module 162 may requestthe video receiver 160 to request the video broadcast/switch module 140to switch the video programming to the requested channel associated withthe recorded video broadcast. Upon receipt of the request, the videobroadcast/switch module 140 switches to the requested channel,signalling the video recording module 172 to transmit the recorded videobroadcast via broadcast/switch module 140 to the STB/DVR 150 for displayon display device 168.
